Yoni, 

You don't play the piano do you?  :>)

If you make the T-line longer the delay should get larger.  
1.Try simplifying the problem by simulating only the T-Line (using
independent voltage sources in place of your drivers) and watch the delay
increase and decrease as you change the length. 
2. Check your probe locations.  Are you really looking at the input and
output?

hi,
i run some simulations, for measuring Tpd from input of the of the =
driver to the output of the driver.=20

                |\
                | \driver               transmission line
     input------------|  =
\---------------------------------------------------LOAD
                |  /out
                |/
I have noticed that the longer my transmission line, the Tpd becomes =
shorter.
does it make sense? as i understand it a longer transmission line means =
more capacitance (and resistance) so the Tpd should be longer, doesn't =
it?
